Kidnap accused Rachel Maree Faul was instrumental in luring a man to an isolated spot at the bottom of the Crown Range where he was beaten up and bundled into a car before being driven off, a District Court jury has heard.

The trial for Faul, 22, the remaining defendant in a 2011 kidnapping case that took place near Queenstown, continued in the Invercargill District Court yesterday. Faul is charged with kidnapping and offering to sell ecstasy.

The high-profile case resulted in several people facing charges relating to the violent assault and kidnapping of Jason Maynard after a drug deal went wrong.

Crown solicitor Mary-Jane Thomas, in her closing address, said Faul was part of a group which, believing it had been ripped off in a drug deal, decided to exact revenge.

Faul arranged by text to meet Mr Maynard at the bottom of the Crown Range and was the driver of a car carrying men who were armed and in disguise, Ms Thomas said. Faul did not think they were going to meet Mr Maynard "to have a happy little chat".

"By the time the two cars left, it was blatantly clear to the two girls driving that they were going with these guys who had changed their clothes for the purpose of an altercation . . . the Crown says the girls played an active role."

When they arrived at the meeting point, Faul sat in the car while five men beat up Mr Maynard, Ms Thomas said.

Mr Maynard was then forced into the back of Faul's car and, with another man from her group also in the car, she drove towards Arrowtown, "not to save [Maynard] but because she intended to confine him in the vehicle", Ms Thomas said.

Faul stopped the car after several minutes and let Mr Maynard out.

"The Crown says [Faul] aided the kidnapping because she drove the car."

However, defence lawyer Jonathan Eaton, in his closing address, said it made no sense for Faul to deliberately kidnap Mr Maynard, her friend.

Faul must have known Mr Maynard was being assaulted "and all of a sudden he is in the back seat of the car", Mr Eaton said.

"And she drives about 4 kilometres, lasting about three minutes, and she stops and he is let out of the car and that's the end of it."

Mr Eaton said there was no premeditated plan to kidnap Mr Maynard. The "boys" had methim at the Crown Range because they wanted their money back.

He said it made no sense that Faul, 19 at the time and with no convictions, would have unlawfully contained Mr Maynard.
